If you're wondering what you can plant in the fall, the answer is almost anything.
Spring may be special, but fall is ideal for planting trees, shrubs, perennials, turf grass, spring-blooming bulbs and cool-season vegetables.
Fall has distinct planting benefits. Autumn's cooler air temperatures are easier on both plants and gardeners. The soil is still warm, allowing roots to grow until the ground freezes. In spring, plants don't grow until the soil warms up.
Fall has more good days for planting than spring does, when rain and other unpredictable weather can make working the soil impossible. And there's a lot more free time for gardening in autumn than in frantic spring.
Fall showers are generally plentiful, but it's easy to deeply water plants if it doesn't rain at least an inch per week. Pests and disease problems fade away in the fall. You don't need fertilizer, either. Fertilizer promotes new, tender growth that can be nipped by winter weather; stop fertilizing by late summer.
It's fine to plant perennials in the fall, especially specimens with large root systems. Fall is a good time to divide and replant your hostas. Peonies should be planted or transplanted in the fall. Avoid planting them too deep -- no more than 2 inches above the bud on the root -- or they won't bloom.
Late summer and early fall is a good times to plant and transplant irises too. Chrysanthemums come into full glory by late summer and early fall, but it's not the ideal time to plant them. Garden mums do best when planted in spring so they get fully established before winter. Sadly, the big, beautiful pots of florist mums you can buy already in bloom at a garden center won't survive the winter if you plant them now. Any fall-planted perennials should be carefully watered until the ground freezes to keep their roots healthy and strong. Don't overwater, but make sure the plants get at least 1 inch of water one time per week.

Cool-season grasses such as bluegrass, fescue, and ryegrass should be fertilized in early September and again in late October or early November to give a boost for earlier spring green-up.
Many vegetables thrive in cool weather, including broccoli, Brussels sprouts, carrots, cabbage, kale, kohlrabi, lettuce, radishes, rutabaga, spinach, and Swiss chard.
Many fall-harvested crops should be planted in early August to give them enough time to mature. Always consult the seed packet to see how many days it takes until maturity, and count backward from your frost date to allow enough time. Lettuce, spinach, and other greens with a short maturity time can be planted later in the season. Extend the growing season by planting them under floating row covers or cold frames that will shield plants from frost but still allow light, air, and water to penetrate.
Many root crops taste sweeter when they're harvested after frost.
